Prevalence of Asymptomatic SARS-CoV-2 Infection
https://www.acpjournals.org/doi/10.7326/M20-3012
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread rapidly throughout the world since the first cases of coronavirus disease 2019 (COVID-19) were observed in December 2019 in Wuhan, China. It has been suspected that infected persons who remain asymptomatic play a significant role in the ongoing pandemic, but their relative number and effect have been uncertain. The authors sought to review and synthesize the available evidence on asymptomatic SARS-CoV-2 infection. Asymptomatic persons seem to account for approximately 40% to 45% of SARS-CoV-2 infections, and they can transmit the virus to others for an extended period, perhaps longer than 14 days. Asymptomatic infection may be associated with subclinical lung abnormalities, as detected by computed tomography. Because of the high risk for silent spread by asymptomatic persons, it is imperative that testing programs include those without symptoms. To supplement conventional diagnostic testing, which is constrained by capacity, cost, and its one-off nature, innovative tactics for public health surveillance, such as crowdsourcing digital wearable data and monitoring sewage sludge, might be helpful.
Key Summary Points
The likelihood that approximately 40% to 45% of those infected with SARS-CoV-2 will remain asymptomatic suggests that the virus might have greater potential than previously estimated to spread silently and deeply through human populations.
Asymptomatic persons can transmit SARS-CoV-2 to others for an extended period, perhaps longer than 14 days.
The absence of COVID-19 symptoms in persons infected with SARS-CoV-2 might not necessarily imply an absence of harm. More research is needed to determine the significance of subclinical lung changes visible on computed tomography scans.

This shit is hideous and we're doing little different than 1918. Data sets are horrible on CV19

And yet in years to come, I think we will realize that in some ways this was worse than 1918.

It usually hurts like hell when a virus or bacteria is fucking up your lungs. You know you are sick.

1918 killed quickly, and that was horrible. This has effects that will linger for the rest of the lives of many who get it.
For the moment we can say that 1918 killed many more people, but when all is said and done I wonder if that will still be true.
If it is not still true, if we end up with many many more deaths, it will be in a large part the fault of the USA.

This virus seems to evade that response.

The inflammation response is the problem, IMO.

You either wear one one or you will be fined and/or jailed.
Free masks for everyone who cannot afford them.
